When you picture doing a science project, you might imagine looking through a microscope or building a model volcano. But science projects can be done anywhere. Many teens get inspired from playing musical instruments to doing gymnastics. All it takes to transform your favorite activities into a science project is identifying a problem you want to solve.

Elizabeth, 14, who is in seventh grade at Davis Drive Middle School in Cary, N. C, designed a program. Her method is based on the golden ratio (比例). This ratio is often used to create pleasing parts in artworks. The ratio also appears in nature. Elizabeth’s data storage strategy helps computers write data evenly (均匀地) across memory devices. This could help such devices last longer.

“As long as I can remember, I’ve been an artistic person,” Elizabeth says, “In fourth grade, my art teacher taught us about the golden ratio. And at that point it was just, you know, something to use when we were painting.” But last year, Elizabeth had to replace the memory in her own computer, thinking the golden ratio might work in information storage, too. Elizabeth tested her golden-ratio technique by running programs on a computer.

But before this project, Elizabeth had no coding experience. To prepare, she spent months reading a textbook on how to code. She says, “It wasn’t like an ‘ah-ha’ moment. Writing programs is such a boring process. But it was just exciting to explore and see the computer actually just doing stuff that I told it to do after those hours.”

“Don’t limit yourself,” Elizabeth adds, “One of the biggest challenges you face is changing your mindset. I never thought that science or computer science would be my kind of thing, but after learning a bit about programming, I found that it was actually a new way to express myself. Words, painting, now programming.”
